Developing a pattern language for flow experiences in video games Philippe Lemay, Ph.D Head of Game design graduate studies University of Montreal CP 6128 Succursale Centre-Ville, Montreal, QC, Canada, H3C 3J7 [email protected] ABSTRACT a child book, a small-scale replica of a World War II plane, Pattern languages have gained widespread acceptance over or a cheaper computer for the masses. the years in the design and computing communities. Thanks to the seminal work of Bjork and Holopainen they also have Patterns abound in natural and artificial worlds. Sequences spread to the video game design community. In order to (of numbers, of letters), cycles (of days and nights, of help game designers grasp fundamental aspects of human seasons) processes (of industrial manufacturing, of experiences, the author is developing a new breed of pattern neurological transmissions), tendencies (of economical language: a pattern language for experience design, and in markets, of fashion), shapes (of cars, of trees) and particular, a pattern language for optimal experiences (or probabilities (of winning at the casino, of an earthquake in flow) in games. Mexico) are kinds of patterns found in nature. The objective of this endeavor is to elaborate a generative The multifaceted nature of patterns is also observable modeling tool that will help designers understand, analyze across literary sources.

The recognition of a INTRODUCTION pattern often leads to use it as a guide, in order to perform Practitioners of many disciplines have attempted to derive certain actions (as a sewing pattern). the fundamental building blocks of their domain and tried to formulate the rules that bind these blocks together. Poets, Patterns have not just been recognized in the natural or built mathematicians, graphic artists, chefs, industrial designers world, but have also been used in several domains, such as and computer scientists, to name just a few, delved into this architecture [2], software design [6, 16], economy [14] and endeavor. more recently game design [4]. Its methodological development have mainly stemmed from the seminal work When Christopher Alexander [2] put forth his idea of a of Christopher Alexander and his colleagues. According to pattern language, although his work was originally applied Alexander, each "pattern describes a problem which occurs to architecture, his approach represented a lingua franca for over and over again in our environment, and then describes researchers and practitioners of various disciplines. By the core of the solution to that problem, in such a way that trying to define the basic constituents of a given field – thus you can use this solution a million times over, without ever codifying its fundamental knowledge – pattern languages doing it the same way twice."

In software design and human computer interaction pattern languages enable designers to elaborate better interactive systems, by taking into account the human cognitive and behavioral intricacies, not just technical requirements. Pattern language projects include User interface design patterns [33, 5, 22], Patterns for speech dialogues for older adults [38], Pattern language for living communication [31], Visualization pattern Figure1. Four language [37] and Patterns for Groupware [17]. They each components of represent interesting attempts to codify knowledge in patterns in game different areas of the human-computer interaction. Some of design these projects target either specific contexts of interaction, particular populations, elements of interaction In the end the availability of patterns for experience design (communication) or interface (dialog boxes, progression will have positive consequences, following Tidwell’s bars and the likes). consequences of pattern languages [33]: Patterns in the game design community 1. gather knowledge of decades of psychological research In game design the most notable endeavor was done by into a coherent corpus; Björk and Holopainen [4].

Many psychological theories elements are the actions, events, closures, end conditions exist that provide (tentative) explanations to these questions, and evaluation function of the game.

Psychologist M.

The resulting language may even be musicians, shepards). Research results constantly point to a included as a fifth component to Bjork’s and Holopainen’s convincing conclusion: activities that are the most intense language.

Csikszentmihalyi labeled this particular state as flow or optimal experience, following comments of surveyed people who experienced this kind of state. Flow experiences 450 have been described as "... holistic sensation(s) that people Conditions and characteristics of flow feel when they act with total involvement" [10].
